BOILER VI'ASHEE.

Application filed December This invention relates to means for washingboi ers, the general object of the invention being to provide a tubularmember pro vided with a plurality of nozzles or ports and which isadapted to be connected with a fluid supply so that water or othercleaning material can be forced through the member, the water or othercleaning fluid escaping through the nozzles or ports against theinterior parts of the boiler to clean the same.

Another object of the invention is to so form the nozzles or portopenings in a man- .ner so that the fluid is given a whirling rotationalmotion which increases its cleaning effect.

This invention also consists in certain othe natures of construction andin the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

, In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a View showing a boiler equipped with one form of my cleaning device.

Figure 2 is a sectional view through one of the nozzle members of thetubular member.

Figure 3 is an end view of said head.

Figure 4 is a view showing a modified form of my invention.

Figure 5 is a sectional View taken through this modification.

Figures 6 and 7 are views of a furthermodification.

Figure 1 shows a plurality of heads 1 connected together by tubes 2 toform a tubular member having its ends suitably connected to parts of theboiler as shown and one end is in connection with a source of cleaningfluid by means of the exterior line 3 so that when the line is opened,the cleaning material will escape through the cleaner heads and come incontact with the interior parts of the boiler to clean the same; Theheads 1 are each formed with a spherical body 2 having opposing endnipples 4 which are threaded to receive the ends of the tubes 2. Eachbody is provided with a series of nozzle openings or ports 5, theopenings or ports being shaped in elongated form and are inclined to.the longitudinal center of the head. Each opening has its longitudinalcenter arranged 1, 1925. Serial no. 151,867.

on a45 angle in relation to the length of the head, as clearly shown inFigure 2 in dotted lines and by this construction, it will be apparentthat tne fluid escaping from the head through the ports will be given awhirli rotational motion which will increase its cleaning effect. Theboiler isprovided with a suitable blow-oif or sludge outlet, and thenozzle openings are directed toward this. outlet as'suggested in Figure1.

The device may be suitably closed at one end and the other end may beconnected with the regular feed line of the boiler, and when inoperation, the cleaning fluid is given a continuous whirling motionwithin the body of the boiler so that the interior parts of the boilerare freed of scale, deposits and other foreign matter and this matter isdivided into small particles and forced out ofthe boiler.

The device can easily be cleaned by allowing water or other fluid toflow through the same in a reverse direction and it can be used as aflue blower by closingone end and at taching the other to a pipeinserted into the tubes and it can also be used as a soot blower and asa draft producer.

Figures 4 and 5 show a modified form of the invention in which a tubularmember 9 is formed with elongated nozzle openings or ports 10. Theseports 10 are each formed by cutting the metal of the tube to form atongue 11 which is pushed outwardly, as shown. These ports 10 arepreferably formed at an angle of 45, with the axis of the tube and theyare progressively staggered around the tube. The tube may have one endclosed and is preferably placed in the boiler by being inserted througha nipple 12 which is threaded in front of the boiler, with the oppositeend of the tube expanded in the nipple. The coupling 13 is then screwedin the nipple 12, with one end engaging the upset portion of the tube 9which holds the parts in position. This coupling 13 may be connectedwith the supply pipe 3.

The arrangement of the ports 10 will also give a rotary motion to thefluid passing through them so that a whirling motion is imparted to thefluid which will increase its cleaning action. This nipple may beintroduced into the boiler through the hole drilled and threaded for theconnecting plug thereof,

thus greatly simplifying the construction and cheapening the cost'ofinstallation.

A die arrangement can be readily introduced into the tube and the portscut by stamping, thereby cheapening the cost over sawing or moulding. Ifa copper tubing is used, it Will not corrode, rust or loosen in itsfastenings and will also give longer service.

The device can be operated by simply manually turning on valves or thevalves can be automatically turned by electrically operated means.

In badly scaled boilers it may be necessary to havethe boiler washedby-theboiler washer anywhere from three to -five minutes per hourwhilethe boiler is in use until the scale is removed. When the boiler isclean, then the washings can be reduced to five or ten minutes perworking day.

Figures 6 and 7 show a modification similar to that shown in Figures 4and 5, but the ports which are indicated bygthe reference numeral 10 areformed by cutting kerfs inthe tube 9. These ports 10 are .inclinedlyarranged, as shown, so as'to also produce a. rotatable movement ofthecleaning-fluid.

What I claim is:

'1; "The combination with a boiler, of a Washing device comprising atubular member horizontally disposed in said boiler in spaced relationto the walls "thereof, said member closed at one endand connected to asupply of cleaning fluid at its opposite end, said member being provided.with .circumferentially and axially spaced ports arranged to dischargein a generally forward and spiral direction withrespect to said member,whereby to induce a rotational movement of the cleaning fluid within theboiler.

2. The combination with a boiler, of a washing device comprising atubular member horizontally disposed in said boiler in spaced relationto the walls thereof, said member closed at one end and connected to asupply or cleaning fluid at its opposite end, said member being providedwith circumferentially and axially spaced ports arranged to dischargetowardthe same end of said member, the ports beingso'shapedand disposedas to effect by their discharge a rotational movement oi the cleaningfluid in the boiler into which they discharge. v

3. The combination with a-boiler, of a device comprising i a malleabletubular member disposed in said boiler in spaced relation to the wallsthereof, said member closed at one end and connected to a supply offluid at its opposite end, said member being provided withcircumferentially and axially spaced ports arranged to discharge towardthe closed end of said member, each of said ports being in part definedby an outwardly-punched, forwardly directed tongue.

In testimony whereof I aflix my signature.

SAMUEL RADWAY.
